CAN OPENER.

Application filed December 23, 1921. Serial No. 524,425.

To all whom it may 00mm:

Be it known that we, JOHN W. BAUER and LAWRENCE E. BAUER, citizens of the United States, residing at Havre de Grace, in the county of Harford and State of Maryland,

have invented certain new and useful Improvements in Can Openers, of which the following is a specification.

This invention relates to improvements in can openers, and has for its object to provide a simple, cheap and efficient device for cutting the tops from cans and especially where the cutting is to be done from the outside under the bead of the can.

The invention consists of the novel construction and arrangement of the parts and combination of parts hereinafter more fully set forth in the following specification and pointed out in detail in the appended claims.

In the accompanying drawing,-

Figure 1 is a side elevation of our inven-.

tion showing the can beingflplaced in position'to be cut.

Figure 2 is a top plan view of Figure 1. Figure 3 is a vertical longitudinal section of Figure 4, with the shaft turned to show the slotted upper end. Figure 4 is a detail plan view of the eccentric and outer end of the arm to which it is secured.

Referring to th accompanying drawings, formin part of this specification, and in which like reference numerals designate like parts throughout the several views thereof, 1 designates an arm having apertures Q in one end for the reception of screws 3 to hold the said arm in position on a table, or other suitable place. Revolubly secured to the under surface of the said arm 1 is a cutting disk 4 having an integral clamping disk 5 on its up er surface and a gear wheel 6 riveted or otherwise secured to upper surface of said clamping. disk 5. Tn the outer end of the arm 1 is revolubly secured an eccentric 7 having a cut-out 8 in its upper edge and two shoulders 9 and 10 on said upper edge. Projecting through the eccentric 7 is a shaft 11 adapted ito revolve independent of said eccentric 7 and'having a clamping disk 12 on its lower end and two recesses 13 in its upper end. Secured to the upper surface of the clamping disk 12 is a gear wheel 14 adapted to mesh with the gear wheel 6. The handle 15 has a bifurcated end 16 which fits astride the upper end of the shaft 11- with the ends projecting into the recesses 13, and a lug 17 on its lower surface adapted to fit into the cut-out 8. The said handle is adapted to slide back and forth so that the lug 17 can be inserted and withdrawn from the cut-out 8. The upper surface of the arm 1 is provided with a pin 19 to limit the revolution, in both directions, of thehandle.

When it is desired to operate the device the handle is set with the lug 17 projecting into the cut-out 8 and the can placed with the bead projecting between the clamping disks as shown in Figure 1 of the drawing. The said handle is then turned to, the right until the shoulder 10 strikes the pin 19, and in making this revolution the eccentric 7 carries the clamping disk 12 back clamping the upper end of the can between the two clampin ing the cutting disk 4 to penetrate the body of the can below the bead. The handle is then moved back until the lug 17 is withdrawn from the cut-out 8, and then again revolved to the right causing the can to be revolved between the clamping disks and the cutting blade to cut the top from the can under the saidbead. When the cutting is completed the handle 1 is moved to force the lug 17 into the cut-out 8 and then the said handle is revolved to the left until the shoulder 9 strikes thepin 19, which movement causes the clamping disks to be moved apart through the action of the cocentric 7, when the can is removed.

Having thus described our invention, what we claim is:

1. A can opener comprising an arm, a cutting disk revolubly mounted under said arm, an eccentric revolubly mounted inothe outer end of said arm and having a -cutout in its upper edge and two shoulders on its upper edge, a shaft revolubly mounted in said eccentric and having a clampingdisk on its lower end, and a handle slidably secured to the upper end of said shaft and having a lug on its lower surface adapted to fit into the cut-out in said eccentric.

2. A can opener comprising an arm having a pin on its upper surface, a cuttlng disk revolubly secured to the under surface of said arm and having a clamping disk on its upper surface, a gear-wheel secured to said clamping disk, an eccentric revolubly secured in the outer end of said arm and having a cut-out in its upper edge and two shoulders on its upper edge, a shaft revodisks 5 and 12 and causice llltl lubly secured in said eccentric and having to fit into the cut-out in the upper edge of a clamping disk on its lower end, a gear the said eccentric.

wheel secured to the clamping disk on said In testimony whereof we afiix our signal0 shift and adapted to mesh with the first tures.

named gear-wheel, and a handle slidably secured to the upper end of the said shaft and JOHN W. BAUER. h'avinga lug on its lower surface adapted LAWRENCE E. BAUER.
